The current 1.0.1 release of PECL mysqlnd_qc does not support PHP 5.4. Version 1.1.0-alpha lifts this limitation.
Prepared statements and unbuffered queries are fully supported.
Thus, the plugin is capable of caching all statements issued with
mysqli or PDO_MySQL, which
are the only two PHP MySQL APIs to offer prepared statement
support.
